Original job description

Please Note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.   At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.  

We are seeking a highly skilled Principal Electrical Engineer to lead the design, development, integration, test, and flight qualification of advanced spaceborne payloads.

This post focuses on the role of Unit Lead (aka Responsible Engineer) in our Phased Array product line, focusing on Ka-band Active Electronically Steered Arrays (AESAs). CesiumAstro AESAs are state-of-the-art electronics assemblies consisting of an antenna element array, RF electronics, digital array control, and power conversion – engineered into a single box using a modular but optimized approach.

The Unit Lead is responsible for both technical definition and execution of a new AESA product. This combines deep, multi-disciplinary technical accountability with responsibility for on-time schedule execution. The project may include the development of new active antenna modules, new RF and power/digital backplanes, new array control and power conversion, and/or new software features, coming together into a qualified, customer-ready product.

The Unit Lead is the leader of the multidisciplinary technical team, the primary point of contact for the program manager, and often a key interface point for our customers. Success in this role requires deep expertise in technical topics as well as project management, leadership, and communication in a fast-paced startup environment.
